A Wide Toe Box Minimalist Walking Boot
The Lems Boulder Boot is a minimalist boot that supports natural foot health. This versatile and lightweight walking boot is flat from heel to toe, possesses a toe box that is widest at the ends of your toes, and is completely collapsible—the perfect footwear for trekking or other outdoor activities, or for around town. Every design element of the Boulder Boot reflects a commitment to anatomical integrity and mobility, encouraging your feet to move, flex, and function the way nature intended. Whether you’re exploring a rugged trail or navigating city streets, this boot helps restore balance, strength, and awareness with every step.
Correct Toes Compatible, Lightweight Design
The Lems Boulder Boot’s upper is made of 100% water-resistant nylon to help keep moisture away from your feet. The boot’s generous toe box is compatible with Correct Toes and allows you to experience the comfort and foot health benefits that come with natural toe splay. This “barely-there” boot contains no heel counter, toe counter, or shank, and it packs away easily, preserving space in your travel bag or luggage. By removing unnecessary structure and bulk, Lems has created a boot that works in harmony with your body’s own support systems. The result is footwear that feels intuitive and freeing—an ideal choice for those seeking a closer connection to the ground beneath them.
Works Great With Other Natural Footgear
This accommodating and flexible-soled boot also works great in combination with other helpful natural footgear, including Injinji toe socks, Pedag metatarsal pads or Strutz Pro foot pads, and Naboso insoles. When paired with complementary natural footgear, this boot becomes part of a holistic system that nurtures long-term foot health and overall well-being. Its lightweight build and adaptable design invite you to experience more comfort, more freedom, and more confidence with every adventure. The Lems Boulder Boot works well in temperatures as low as 15 degrees F (about -10 degrees C) when used with an appropriate sock. Each Lems Boulder Boot weighs about 10 oz.
Note: If you are new to using Lems footwear, we recommend that you start in slowly, gradually building up your wear-time and giving your body the chance to adapt to the thinner soles and the increased workload on your feet.

To get the most out of your Lems Boulder Boots (Vegan Black), the manufacturer recommends that you order a half-size up from your normal US shoe size. For example, if you normally wear a men's US size 11 shoe, consider ordering an 11.5 in the Lems Boulder Boot Vegan Black.
If you're on the fence about what size to order, consider ordering both sizes and then simply return the size that doesn't fit as well for a refund. If you have concerns about sizing, feel free to contact us or Lems customer service.
Sizing Tip #1: To create additional roominess within the boot, we suggest removing the included (optional) boot liner/insole; this action does not, in any way, affect the performance of the boot. Optionally, and to enhance balance, posture, agility, and general foot/body awareness, you might consider adding thin, flexible Naboso insoles instead.
Sizing Tip #2: Correct Toes toe spacers will often add width and length to the foot. If you’re planning to wear Correct Toes with your footwear, we recommend sizing up, especially if you are on the border between sizes.
